Hi. I am worried that my maze coral is not happy. I have had it for about 6 - 8 weeks. It appears to have started bleaching around some of the edges. This started about 2 a week or 10 days ago. My initial reaction is that my lighting is not strong enough. Yesterday I moved the coral to a position about one third from the top of the tank. Previously it was on the bottom. Reading other threads I know that maze corals do not need heavy lighting but I know mine is not very powerful which is why I have moved the coral higher. In the past after lights-out I have observed short feeder tentacles but recently I have not seen this behavior. Have I done the right thing moving it higher or should I have moved it into a shaded area?
All other corals seem to be doing just fine. I feed them rotifers (live) about twice a week and coral food about once a week. I target feed where possible.
Other info that might help:
Tank temp : 25C Sg 1.025. pH 8.1 Nitrates and Ph near 0. Alk 9.6 Ca 425 Mg 1250 Sr 10. Lighting is 2X35Watt T5's with reflectors.. Highlite Marine white and Blue actinic.
Thanks to anyone who has any ideas.
